Journal ArticleDOI
Spread spectrum image steganography
TL;DR: A new method of digital Steganography, entitled spread spectrum image steganography (SSIS), which hides and recovers a message of substantial length within digital imagery while maintaining the original image size and dynamic range.
Proceedings ArticleDOI
A multiresolution watermark for digital images
TL;DR: A new multiresolution watermarking method based on the discrete wavelet transform (DWT), where Pseudo-random codes are added to the large coefficients at the high and middle frequency bands of the DWT of an image.
Book ChapterDOI
Image Noise Models
TL;DR: In this article, it is shown that additive Gaussian noise is the limiting behavior of other noises, e.g., photon counting noise and film grain noise, which is a part of almost any signal.
Journal ArticleDOI
Wavelet transform based watermark for digital images.
TL;DR: It is shown that this multiresolution watermarking method is more robust to proposed methods to some common image distortions, such as the wavelet transform based image compression, image rescaling/stretching and image halftoning.
Journal ArticleDOI
LUM filters: a class of rank-order-based filters for smoothing and sharpening
TL;DR: Lower-upper-middle (LUM) filters as mentioned in this paper are a class of rank-order-based filters, which can be designed for smoothing and sharpening, or outlier rejection.
